Introduction and Aims

Pitch in Communication

1 2 3


  • Pitch carries information in nonhuman vocalisations, human music, and human speech
    • Physical
    • Emotional
    • Social
    • Semantic
  • Pitch: A percept of sound correlated primarily with fundamental frequency
  • Fundamental frequency (\(f_0\)): The lowest frequency of the vocal fold vibration

Primate evolutionary relationships.

Pitch in Human Language

Macroprosody

  • The positions, number, alignment, heights, and shape of \(f_0\) peaks (Kohler, 1990)
  • Stress and intonation
  • Pitch accent and lexical tone

Microprosody

  • Vowel intrinsic \(f_0\) due to vowel height
  • Consonant-related \(f_0\) perturbations
  • \(f_0\) masking or variations in non-modal phonation

Macroprosody: Lexical Tone

Standard Mandarin tones
